Campbell, 22, scored in the Emirates Cup against Benfica in pre-season before making his Premier League debut in the 2-2 draw at Everton on Saturday

"I am very happy to be here," Campbell told Arsenal's official website. "It has been three years on loan at different clubs but finally now I can settle in here. I want to prove what I am capable of.

"The Premier League is different to the leagues I've played in. It's a very physical competition where the ball goes very quickly from one box to the other, but at the same time I am part of a team that puts a passing game into practice. Arsenal has great players and the kind of football we play suits my style.

"I'm at a very competitive club with many top-class players in the squad. You have to work really hard even to stay on the bench, let alone to get a spot in the line up.

"Thank god I performed well with my national team at the World Cup - the fans could see what I am capable of. Now it's time for me to prove my qualities, I have to work hard during training and make the most of any single opportunity the manager may give me."

With Olivier Giroud potentially facing three months on the sidelines due to an ankle injury, Campbell could have the perfect chance to stake a claim for a first-team spot in Arsenal's attack.

Lukas Podolski was also believed to be on his way out with Juventus linked with a £10 million move, though Giroud's injury could force Arsene Wenger to keep hold of the German.

Campbell could be involved for Arsenal's crunch Champions League qualifier against Besiktas on Wednesday, though Yaya Sanogo could return from injury having missed the first leg.
